A dashcam can provide valuable evidence, but it does not “never lie” or automatically decide fault. Preserve the complete original and understand what the camera could—and could not—record. Lens position, exposure, missing audio and clock settings can affect interpretation.
Protect the recording from routine overwrite
Once safe, follow the manufacturer’s instructions for preserving an incident recording. Do not troubleshoot a device while driving or delay emergency assistance. Keep the original storage medium where practical and make a separate working copy.
Save relevant footage before and after impact, not only the most dramatic seconds. Preserve rear or cabin recordings if available. Avoid deleting material because it appears unfavorable.
Keep context with the file
Record the device model, camera position and known clock issue. If the displayed time is wrong, explain that separately rather than altering the original. Retain associated files and messages about how the footage was obtained.
A shared social-media clip may be compressed or incomplete. Keep the source recording in addition to any viewing copy.
Do not overread speed or distance
Wide-angle lenses can distort perceived distances. A GPS display may require validation and does not automatically establish another vehicle’s speed. Qualified analysis may be needed for measurements or a disputed sequence.
A camera may miss a signal, side impact or earlier event outside its view. Compare the footage with photographs, witness accounts and the agency crash report.
Check installation and recording questions separately
Before installation or changing audio settings, check current California placement and privacy requirements and the manufacturer’s safety instructions. Do not assume every windshield position is permitted or that a sticker resolves every consent issue.
The earlier article’s categorical mounting, privacy and police-seizure answers were too broad. Those questions require the specific device, circumstances and applicable law; do not resist lawful instructions based on a blog post.
Share evidence through an appropriate channel
Keep a record of the copy supplied and recipient. Avoid public posting that exposes private information or creates an incomplete account. If a recording request or dispute arises, obtain individual advice and preserve the material.
